Hva betyr feilkoden?
The SUM receives a supply voltage that is too low. The causes are a battery voltage that is too low, or contact resistance and oxidation in the connections.
Mulige årsaker
- Battery voltage too low
- Contact resistance or oxidation in the connectors
Hva du kan gjøre
- 1Check the condition and charging of the battery; a weak battery can produce this code
- 2Check that the battery terminals and earth connections are clean and tight
- 3If you have a diagnostic tool, compare the supply voltage to the SUM in live data with the battery voltage
- 4If the fault returns, have a workshop with diagnostic equipment check the supply to the SUM and the connectors
Symptomer du kan merke2
- A message appears in the information display
- The Four-C function does not work
Hva feilen kan påvirke1
